Enantioseparation of amino acid derivatives on an immobilized network polymer derived from L-tartaric acid.

Seven structurally related amino acid derivatives were successfully enantioseparated by HPLC with a commercially available column containing a chiral immobilized network polymer derived from L-tartaric acid. The experiments were carried out under normal-phase conditions. All the solutes could be baseline separated using n-hexane/2-propanol (95/5) as eluent at a flow rate of 1 ml/min at 25 degrees C, with reasonable retention time (<12 min).

[18F-Fluorodeoxyglucose uptake in hepatocellular carcinoma on positron emission tomography correlates with alpha-fetoprotein].

Objective: To investigate whether (18)F-fluorodexyglucose (FDG) uptake in the primary hepatocellular carcinoma (HCC) correlates with serum alpha-fetoprotein (AFP).

Methods: Forty-five patients with histologically confirmed HCC underwent whole-body (18)F-FDG PET examination. Standardized uptake value (SUV) and tumor-to-nontumor ratio of the SUV (SUVratio) were calculated, and the relationship between serum AFP and glucose metabolism in HCC was analyzed.
